A vortex suppression device is provided which includes a plurality of spaced apart porous panels arranged generally parallel with respect to each other for placement adjacent a suction pipe inlet. The panels of the suppression device are oriented generally perpendicular to, or parallel to the suction pipe inlet. The device serves to prevent formation of a sufficiently strong vortex capable of pulling a continuous gas core into the suction piping.

A foam detector apparatus has a detector probe for detecting the presence of foam in a test sample, with the probe held above the test sample surface and indicating foaming when foam rises from the test sample surface and contacts the detector probe. The probe has a low thermal mass measuring surface for detecting contact with foam, with the measuring surface heated to a temperature above the tempering temperature of the test sample. When the liquid portion of the foam contacts the heated measuring surface, the temperature of the low thermal mass surface quickly drops to the tempering temperature of the sample, thereby indicating foam.

Foam detector apparatus and method

The present invention comprises a calorimeter apparatus having a very low thermal mass ratio of test cell to test sample so as to minimize heat sink effects on the test sample during a chemical reaction. The heater control algorithm of the present invention comprises a calibration stage in which the heater is tuned to the particular test conditions at hand, and a test stage in which the heater may control the sample in a ramping mode and in an adiabatic mode. Because the sample may be tested in an adiabatic mode, greatly improved sensitivity in detection of reaction onset may be achieved, and measured data is truly adiabatic and need not be adjusted for analysis. The present invention further comprises a calorimeter apparatus having a foam detector for detecting the presence of foam in the test sample.

Methods and apparatus are disclosed for taking advantage of a heat exchange relation between a liquid coolant and a protected liquid, whereby vaporization of the liquid coolant withdraws heat from the body of the protected liquid or an exterior heat source in order to prevent undue temperature rise within the body of the protected liquid.

An acoustical wave trap is combined with the rupture disc or relief valve used in vessels for storing potentially explosive materials. The acoustical wave trap operates to substantially reduce the magnitude of the rarefaction wave produced within the vessel when the rupture disc or relief valve opens, and thereby simplifies the pressure relief requirements.

A reactor core for a gas-cooled reactor, which core is composed of a plurality of prismatic bodies (2) of graphite containing nuclear fuel and having a top wall, a bottom wall and a plurality of vertically extending side walls, each graphite body (2) being provided with a plurality of first coolant flow channels (4) extending vertically between the top wall and the bottom wall, and with a plurality of second coolant flow channels (6) extending transversely to the first channels (4) and each interconnecting a plurality of the first channels (4).

A stable isothermal calorimeter wherein the material under study is contained in a thermally conductive reactor vessel which is surrounded by a heat transfer fluid. The material is maintained at the boiling point of the heat transfer fluid which is in turn cntrolled by controlling the pressure of the fluid's vapor space. The heat transfer fluid is vaporized by the heat released by exothermal reaction of the material under study and the vaporized fluid condensed in a condenser. The rate of liquid accumulation in the condenser is proportional to the energy release rate of the material.

Stable isothermal calorimeter

A chemical reactor vessel is provided with a plurality of tubes filled with a heat exchange fluid. The tubes are disposed in a heat exchange relationship with the reactor contents and are coupled via pressure sensitive rupture discs and a header to a reservoir. Upon overheating of the reactor contents, excess heat is absorbed by the heat exchange fluid which boils off at a predetermined vaporization temperature and vapor pressure to rupture the discs and thereby establish fluid communication between the tubes and a heat exchange fluid contained in the reservoir, and thereby maintaining the reactor contents at a preselected safe temperature.

Chemical reactor

Micro-scale chemical process simulation apparatus is disclosed which is useful for design of full-scale processes and associated equipment as well as emergency relief systems. A thin-walled vessel for receiving a quantity of the material to be evaluated is supportd within and thermally insulated from the walls of a surrounding containment unit. A guard heater is provided around the vessel and temperature thermocouples and pressure transducers are strategically located to monitor the temperature conditions existing in the material in the vessel as well as the pressure within the vessel and the containment unit respectively. Fluid may be selectively introduced into or exhausted from the containment unit to maintain a required pressure balance between the interior of the vessel and that of the containment unit. The wall thickness of the pilot vessel is such that the phi factor defined by the thermal mass of the material plus the thermal mass of the vessel divided by the thermal mass of the material is not significantly greater than the same ratio of thermal masses which obtain during a full-scale chemical operation in a pressure vessel.
